Study Summary

The purpose of this study is to compare the effects (good and bad) of subantimicrobial dose doxycycline on the irregular bleeding women experience when taking continuous oral contraceptive pills. This research is being done because currently, there is no effective treatment for this condition. Findings from this study could help to decrease the side effects of birth control pills and decrease unplanned pregnancies.

Primary Outcome

Baseline Matrix Metalloproteinase expression (activity level) will be determined on day 19-21 of cycle 1. During cycle 2, when women are taking the cyclic oral contraceptive, the endometrial biopsy will be performed between cycle day 19-21 (study day 47-49), prior to endometrial degradation and activity level will be noted. Of note, the outcome is MMP activity level, not a change in level.
